Abstract
This paper reports an investigation of collaborative learning in mathematics classes that
sought to identify patterns of participation in small-group activities. Videotapes of lessons
in three senior mathematics classes were studied, and, using positioning theory, a range of
subject positions available to students during small-group collaborative activities was
determined. A student’s pattern of participation was defined as the combination of
positions regularly taken up by that student, and groups of students with common patterns
of participation were identified. Implications for collaborative learning are discussed.
